v CAN-STUFEING MACHINE.

To all whom it may concern:

Be it known that I, RoBEnT J. VORKMAiV,

a 'citizen-of the United States, residing in can arrestingm'echanism adapted toarrest cans on a draper and under a filling orstuffing spout;

Third, to provide a simple, eificient and improved means for conveying a, viscous material from a hopper into a can; s

Fourth, to providean improved ad ustable mechanism to force or feed various predetermined amounts of a viscous material into a can or the like.

. I accomplish these several ob ects by means of thepreferred form of the device disclosed in the drawings forming a part of the present specification wherein llke characters of reference are used to designate similar parts throughout the said specification and drawings and in which- Figure 1 is a broken plan view of my improved stuffing machine, a portion of the hopper being. in section;

Fig. 2 is a broken front elevation;

Fig. 3 is a transverse sectional view. of the machine; Pg. 4 is a ling cans for,the operating of the stuffing conveyer; and e s Fig. 5 is a section taken on line 5- 5 of Fig. 3 in the direction indicated.

Referring to the drawings the numeral 1 is used to designate a suitable frame to the upper portion. of which issecured a hopper 2, having a dispensing spout 3 with a depending portion 4 thereto."

Rotatably mounted within the hopper 2 and spout 3 is a worm conveyer 6 whose shaft 7 extends beyond the spout 3 and is provided with a chain sprocket 8.

A: amper 9 is Q mounted upon suitable Specification of Letters Patent.

rollers 11 operated from an independent source, not shown, and is arranged to carry cans 12 under and past the depending portion 1 of the spout 3, the purpose of which will hereinafter be more fully described.

A shutter 14 is arranged under the portion 4: of thespout 3and is pivotally mounted upon the frame 1 as at 16; The otherend of the shutter 14: is connected to an operating lever 17 pivotally mounted as at 18 and arranged to beoperated by means of a cam 19 and on a driving shaft 20 rotatably mounted within the lower portion of 'the frame 1.

The shutter 14 is normally held in a closed position by means of a suitable spring 34, secured above the fulcrum or pivotal point 18 of the operating lever 17, the other end otally mounted to swing ina horizontal plane to carry a gear 27 into and out of mesh with the gear 24: 011 the driving shaft 20 but such engaging relation is normally prevented by means of an adjustable cam plate 29, on the shaft 20, provided with slidably mounted sections 31 and 32. p

A spring 36 seoured'to the shaft 20 and counter shaft 26 tends to hold a roller 37 on the counter shaft 26 onto the peripheries of the cam plate 29' and the sectors 31 and 32 soth at when the space between the ends of the said cam sectors 31 and 32 is encountered" by the rotation ofthe shaft 20 the tension of said spring36 will move the gear 27 i into mesh withthe gear 24 and thereby rotate the counter shaft 26.

The counter shaft 26 is also provided with a sprocket 38 provided with a chain 39 connecting with thesprocket pinion 8 on the outer end of the worm shaft 7 The cans 12 areguided in a precise path directly under the spout 3 and depending portion. 4 thereof by means of strips ll so as to properly aline the said cans 12 to receive the contentsfrom' said spout.

The operation is as follows: In the present instance the hopper is filled with a viscous mass a predetermined portion of which is tobe deposited into successive cane 12 astheirpro giess is temporarily ar at its further progress is temporarily arrested by the slidable rod 23 which is moved trans-- versely across the path of the can, to arrest said can and impede further progress, by means of the cam 21 on the driving shaft 20 and the operating rod or lever 22.

Simultaneously the cam 19 operates the operating lever 17 to open the shutter 1% under the spout 4.- as disclosed in dotted lines in Fig. 5 of the drawings, and against the tension of the spring 3 1. At the same time the sector plate 32 permits the spring 36 to move the roller 37 and counter shaft 26 to a position where the gear or pinion 27 on said shaft 26 will mesh with and be driven by the gear 2 1 on the shaft 20.

This Will cause the counter shaft 26 and the worm conveyer 6 to be rotated to force or convey a portion of the viscous mass or contents of the hopper 2 through the spout 3 and depending portion 4 thereof into the can 12.

The amount of viscous contents conveyed from the hopper 2 to the can 12 will be in direct proportion to the space between the end of the sector 32 and the beginning of the sector 31. "As these sectors overlap at their adjacent ends, as disclosed in Figs. 1,

2, 3 and t ofthe drawings, it is obvious that a continuous periphery will be formed of the adjoining sectors 31 and 32 to prevent the meshing of the gears 27 and 24. As these sectors are slidably mounted upon the cam plate 29 it is obvious that the operating period of the conveyer 6 to convey a portion of the viscous mass into the cans 12 will vary as the space between the open ends of the sectors 31 and 32 is adjusted.

Therefore the predetermined amount of the contents of the hopper 2 be forced or conveyed into the cans 12 may also be adjusted and varied for various size cans.

hen the requisite amount of matter has been forced into the cans 12 simultaneously the beveled 0r inclined end 43 of the sector 31 will engage the roller 37 and unmesh or disengage the gear 27 from the gear 2 1 to prevent the further operation of the conveyer 6 and the feeding or conveying of the contents of the hopper 2 into the can 12; the cam 19 will operate the operating lever 17 to permit thespring 32 to close the shutter 14; and the cam 21 will operate the rod 23 and withdraw the same from the path of the can 12 thereby permitting the draper 9 to convey said can from under and past the depending portion, of the spout 3.

.As soon as the approximate center of the released can 12 has passed the center line of the spout 4 the cam 21 again operates to arrest the progress of successive cans and the above described operation is repeated.

' It is obvious from the foregoin that I have provided an improved can stufiing machine adapted to feed or convey predetermined amounts of a viscous content from. the hopper into successive cans as Well as improved means for temporarily arresting the progress of the cans, and adjustable means for determining the amount of the 7 contents from the hopper; a conveyer to con vey the contents from the hopper to a can under the spout; means for arresting cans under the spout; and means for operating the shutter, conveyer and can arresting means whereby ,a portion of the contents from the hopper may bedeposited through the spout into successive cans. v
